The ARP 200-6022 is a high-performance connecting rod bolt kit designed as a replacement for Venolia and BRC aluminum connecting rods. This 2-piece kit includes washers and features ARP's 8740 chrome moly alloy construction, delivering the strength and reliability demanded by high-performance and racing engines.
Why ARP Rod Bolts Are Superior:
The connecting rod bolt has historically been the weakest link in any connecting rod assembly. ARP addresses this critical issue with precision-engineered fasteners that offer up to 10 times the fatigue strength of competitor bolts. Many leading connecting rod manufacturers specify ARP bolts as original equipment, recognizing their superior quality and reliability. Each bolt is proudly stamped with the ARP name as assurance of quality.
About 8740 Chrome Moly Material:
The 8740 chrome moly steel used in this kit is a quench and temper alloy delivering tensile strengths between 180,000 and 210,000 psi. While considered moderate strength by today's standards, 8740 chrome moly offers excellent toughness and adequate fatigue properties for most racing applications. This material provides a cost-effective solution with the strength needed to handle anticipated loads plus a safety margin for occasional overloads.
Manufacturing Excellence:
- Forged in-house at ARP using only the finest quality materials
- Heat-treated using special vertical racks to assure complete 360-degree penetration
- Threads rolled after heat-treat to provide up to 10 times longer fatigue strength
- Precision CNC-machined to exacting specifications
- Specially designed for optimum reliability in each application
Wave-Loc Technology Benefits:
- Wave-Loc surface contacts the rod and cap for optimum alignment and reduction of fluctuating stress
- Provides snug interference fit (.001 to .005 range) for OEM connecting rods despite wide factory tolerances
- Superior material grain flow compared to knurled bolts that have sharp edges and stress risers
- Virtually eliminates galling and scoring with smooth contact surfaces
Important Maintenance Note:
It is critically important to monitor the stretch of each bolt and replace it when it has permanently elongated by .0005 inch to ensure continued reliability and safety.
